Abstract
The reaction of praseodymium nitrate and 4-tert-butylbenzoic acid (tBBAH) in aqueous solution yielded the dinuclear title complex, [Pr2(C11H13O2)6(C11H14O2)2(H2O)2], which has non-crystallographic Ci symmetry. The two PrIII ions are linked by two bridging and two bridging–chelating tBBA ligands, with a Pr⋯Pr separation of 4.0817 (9) Å. Each PrIII ion is nine-coordinated by one chelating tBBA ion, one monodentate tBBAH ligand and one water molecule in a distorted tricapped trigonal–prismatic environment. The complex molecules are linked into infinite chains along the c axis by intermolecular O—H⋯O hydrogen bonds.

In continuation to our research (Yang et al, 2010), we report the preparation and crystal structure of a new PrIII complex obtained in the reaction with 4-tert-butyl-benzoic acid
